My intent was to make it easier for people to setup environments that demonstrate the SQL problem they are attempting to solve, then post the link to StackOverflow (or something similar) and have people go there and attempt to solve it, much the same as jsfiddle.net is used to solve JavaScript questions.

You can use myLittleAdmin (for SQL Server and MSDE) to test your queries on SQL Server 2000. This is actually a live demo app for myLittleAdmin, a web-based SQL Server and MSDE Database administration tool

I don't know of any online databases you can use, however if the issue is that you need a simple database to check SQL statements as you don't have access to your production one. You could always install the Oracle Express (XE) Edition which is free and small.
